Fig. 1 is the schematic diagram that the equipment in the mobile radio station is shown.More specifically, Fig. 1 illustrates arrangement and the configuration for the mobile radio station 100 that uses when the wireless signal that receives from global position system (SPS), Wireless Telecom Equipment etc.Mobile radio station 100 comprises the circuit 102 that can realize the algorithm such as the digital signal processing algorithm that is used for the wireless signal detection or catches.

Mobile radio station 100 can comprise in order to receive the antenna 120 of wireless signal.Wireless signal can be any in the radio access technologies described below (RAT).Can wireless signal be received in radio frequency (RF) unit 122 with mode as known in the art.Interface 124 as shown in fig. 1 can be in response to radio frequency unit 122.Interface 124 can comprise one or more assemblies---comprise link 126,126, in order to handle wireless signal and this signal is received in the circuit 102 for further processing.

Primary processor 104 can arrive bus 110 and data and/or control signal interface via interface 116,116 via bus/memory interface 112.Such interface can be optional, and comprises that other assemblies of low-power processor described below can communicate by letter with primary processor 104 according to any known way.

Fig. 1 also illustrates and can have still less computing capability and consume the still less low-power processor 106 of power than primary processor 104.And low-power processor 106 can be configured to optimization and be used for low-power operation.Like this, primary processor 104 can be operated under park mode and low-power processor 106 is operated sustainably or compare with high duty cycle operation with primary processor 104, thereby saves power.Low-power processor 106 can also comprise how limited interface and memory.Low-power processor 106 can act on input or other inputs that supervision receives via interface 124, link 126, and this is as known in the art.Like this, low-power processor 106 can monitor input, signal, order or any other data known in the art that receive in the mobile radio station 100 or generate.Low-power processor 106 also can act on to handle from the data of input, buffering etc., and will import storage in memory 108 for example.Except that handling and cushioning, this low-power processor can also filter, simplify and/or combinatorial input.By at some time durations operation low power processor 106 but not primary processor 104, just can reduce the total power consumption of circuit.Below associating Fig. 2 discusses method of operation in more detail.

The arrangement that it should be noted that the various assemblies shown in Fig. 1 only is exemplary.Like this, circuit 102 can comprise more or less assembly, different arrangement of more or less assembly or the like is arranged.The arrangement of Fig. 1 is exemplary and has conceived other and arranged, as long as circuit 102 comprises the low-power processor 106 that allows primary processor 104 can enter park mode.And in order to reduce manufacturing cost and/or to reduce component size, low-power processor 106 can together be integrated on the same chip with primary processor 104, can be integrated in one or more sensor devices such as RF unit 122, or the like.To unite Fig. 2 now method of operation will be discussed.

Fig. 2 is the flow chart that the method that can use with the equipment of Fig. 1 is shown.Particularly, Fig. 2 illustrates the method for operation of mobile radio station when being in park mode 200 such as mobile radio station 100.Mobile radio station 100 can in response in several criterions any and enter park mode.These criterions can comprise user's inertia a period of time, receive inertia aspect the wireless signal, by the determined insignificant position change of sps signal etc.As shown in step 202, primary processor 104 can be placed in park mode after reaching above-mentioned criterion.Park mode can allow primary processor 104 to forbid by it and save power.Primary processor 104 can not be manipulated into as prior art revives to high-frequency.Instead, low-power processor 106 can be activated as shown in step 204.Low-power processor 106 can provide and 104 identical function for monitoring that can provide between each waking with generation in the prior art of primary processor.
